NAME¶

sphinx_cont_seg - Segment a waveform file into non-silence regions

SYNOPSIS¶

sphinx_cont_seg [ options ]...

DESCRIPTION¶

This program reads an input file and segments it into individual non-silence regions. It can process either file or read data from microphone. Use following arguments:

-adcdev

of audio device to use for input.

-alpha

Preemphasis parameter

-argfile

file giving extra arguments.

-dither

Add 1/2-bit noise

-doublebw

Use double bandwidth filters (same center freq)

-frate

Frame rate

-infile

of audio file to use for input.

-input_endian

Endianness of input data, big or little, ignored if NIST or MS Wav

-lifter

Length of sin-curve for liftering, or 0 for no liftering.

-logspec

Write out logspectral files instead of cepstra

-lowerf

Lower edge of filters

-ncep

Number of cep coefficients

-nfft

Size of FFT

-nfilt

Number of filter banks

-remove_dc

Remove DC offset from each frame

-remove_noise

Remove noise with spectral subtraction in mel-energies

-remove_silence

Enables VAD, removes silence frames from processing

-round_filters

Round mel filter frequencies to DFT points

-samprate

Sampling rate

-seed

Seed for random number generator; if less than zero, pick our own

-singlefile

a single cleaned file.

-smoothspec

Write out cepstral-smoothed logspectral files

-transform

Which type of transform to use to calculate cepstra (legacy, dct, or htk)

-unit_area

Normalize mel filters to unit area

-upperf

Upper edge of filters

-vad_postspeech

Num of silence frames to keep after from speech to silence.

-vad_prespeech

Num of speech frames to keep before silence to speech.

-vad_startspeech

Num of speech frames to trigger vad from silence to speech.

-vad_threshold

Threshold for decision between noise and silence frames. Log-ratio between signal level and noise level.

-verbose

Show input filenames

-warp_params

defining the warping function

-warp_type

Warping function type (or shape)

-wlen

Hamming window length
